Blue ink powder and its preparation method

Abstract

The invention discloses a blue ink power and manufacturing method of ink power. Specifically, the invention is the ink power used for a color copying machine, a color printer, a color facsimile apparatus and a color press and the manufacturing method of the ink power. The invention is made of raw materials such as emulsion polymerization high molecular resin, blue pigment, blue magnetic particle,charge controlling agent, wax, hydrotropism dispersant, silica, hexamethy azane and dimethyl dichlorosilane. The emulsion polymerization high molecular resin, the charge controlling agent, the blue pigment, the blue magnetic particle, the hydrotropism dispersant and the wax are put together to be made into solution by being evenly mixed. The solution is evaporated into granules by a spray dryer under 160 DEG C to 300 DEG C. And then, the granules are selected with the silica, hexamethy azane and the dimethyl dichlorosilane added and evenly mixed, which makes the ink power. The blue ink power has low production cost. In addition, the blue ink power does not cause environmental pollution.

Description

technical field [0001] The invention relates to a toner and a preparation method thereof. Specifically, it relates to blue toner for color copiers, color printers, color facsimile machines and color printing machines and a preparation method thereof. Background technique [0002] At present, the blue toners used in color copiers, color printers, color fax machines and color printing machines are all emulsion polymerized toners. This emulsion polymerization toner is mainly made of other auxiliary materials such as emulsion, pigment and crosslinking agent. The preparation method is as follows: first put emulsion, pigment, cross-linking agent and other auxiliary materials together, and uniformly stir to make granular materials. Then, acid and detergent are added to clean the granular materials, and the floating materials on the granular materials are washed away. Afterwards, the washed granular material is dried. Finally, it is prepared by adding auxiliary materials such as...

Problems solved by technology

Since this blue toner needs to be cleaned with a large amount of water during the production process, and 50 to 100 tons of water is needed for each ton of product produced, not only the waste of water resources is serious, the production cost is high, but also the cost after cleaning The discharge of water will pollute the environment
